While over half of all web traffic now occurring through mobile devices, it would seem more important than ever for websites to be designed and fully optimised for smartphone or tablet viewing. However, despite usage skyrocketing, mobile and tablet device conversion rates are stuck at just 21% of all online revenue.

According to the Economist Intelligence Unit, 21% of people believe mobile devices take too long to process requests. 28% find the retailer’s site too difficult to make a purchase. Another 17% find retailer apps too confusing. Finally, a further 31% find they are concerned about data security.

So with this in mind – what can be done to ensure websites are inspiring real and long-term smartphone conversion?
